Definitions

  • the present invention refers to a heating system, and in particular to a control device intended for use with a heat pump according to the preamble to Claim 1.
  • the present invention also refers to a control method for use with a heat pump according to the preamble to Claim 15, and a heat pump and a heating system.
  • Heat pumps are a type of heating system that is becoming increasingly popular as energy prices increase.
  • Heat pumps for houses are designed to produce both hot water for taps and hot water for radiators.
  • the heat for the house is normally distributed by means of underfloor heating loops or radiators, which can sometimes be provided with fans .
  • the hot water for taps is usually stored in an accumulator in- or beside the heat pump, and consists in principle of a water tank in which hot tap water is heated and stored in order to make possible an instantaneous supply of hot water that is larger than what the heating system can produce instantaneously.
  • the hot water can be heated up during the night to enable more hot water to be drawn off during the day.
  • this type of water heating there is no limit, in principle, to the temperature to which the water in the hot water reservoir can be heated, which enables a large number of litres of blended hot water to be drawn off when the reservoir is fully heated up.
  • the heating of the hot water takes place at more frequent intervals.
  • the heating up of the hot water takes place in the hot water reservoir, the so-called secondary water or the hot tap water, of the so-called primary water that is heated up via the heat pump loops.
  • the water-heating temperature that is possible is limited by the temperature to which the heat pump is able to heat the primary water, there is a limit to the temperature to which the secondary water can be heated.
  • hot tap water for baths and showers should be at least 40°C at the tap.
  • regulations that say that the temperature in an accumulating hot water reservoir must be at least 50°C.
  • all hot water should be heated up to at least 60°C at regular intervals.
  • An object of the present invention is to provide a control device for a heat pump that can provide a larger quantity of secondary water at a lower cost. This object is achieved, according to a first aspect of the invention, by a control device according to Claim 1, a method according to Claim 15, and also by a heat pump according to Claim 26 and a heating system according to Claim 27.
  • the control device which is intended for use with a heat pump with an evaporator and a condenser in which a heat transfer medium in a heat transfer circuit that is heated up by means of the evaporator and a compressor is arranged to transfer heat to a main liquid flow via a first heat exchanger part and a heat exchanger part, includes devices for, at least in a heating mode, diverting a partial flow from the said main water flow for passage through the second heat exchanger part.
  • This has the advantage that the lower flow changes significantly the ratio between heat transfer surface and flow, in comparison with known technology, which has the result that the partial flow can be heated up to a considerably higher temperature than was previously the case and, in addition, at a considerably lower cost.
  • the partial flow can then be used to heat up the secondary water to an essentially hotter temperature than was previously the case.
  • the said partial flow can be diverted after the passage of the main liquid flow through the first heat exchanger part. This has the advantage that the partial flow is already partially heated up when it reaches the second heat exchanger part.
  • the device can comprise means for taking the heated partial flow through or into a water tank for transferring heat from the partial flow to water in the tank during the passage of the partial flow. This means that accumulated water at a high temperature can be obtained at a low heating cost.
  • the device can, in addition, comprise a control device for regulating the proportion of the partial flow in relation to the total flow.
  • the control device can, for example, consist of an adjustable shunt valve or throttle valve.
  • the flow of the partial flow can be regulated so that it is ensured at all times that the temperature of the flow that goes in at the top of the water tank is not less than a particular temperature, for example, 5O 0 C.
  • the water flows can be regulated at all times as reguired, for example at certain times hot water production can be given priority, while at other times heating can be given priority.
  • the regulation is preferably controlled by means of the heat pump's control computer.
  • the return flow of the partial flow and the return flow of the hot water can be connected together at the cold water side of the first heat exchanger part. This has the advantage that energy accumulated in the heating system can be "borrowed” occasionally to increase the production of hot water.
  • the first heat exchanger part can essentially consist of a condenser, and the second heat exchanger part can essentially consist of a hot gas heat exchanger. This has the advantage that the hot gas can heat the partial flow to a very high temperature .
  • Figure 1 shows in general a heat pump according to known technology.
  • Figures 2a-e show different operating situations with associated enthalpy diagrams for an exemplary heat pump according to known technology.

  • the heat pump 10 is provided with a control computer 12, that controls and monitors diverse functions in the heat pump. Examples of such functions can be setting and/or monitoring of working temperatures for the heat pump's compressor, indoor and outdoor temperatures, adjustment of heat curves, control of room temperatures depending upon the time of day or in the event of absence from home for holidays, etc. Additional examples will be given below.
  • a user can communicate with the control computer 12 via a display and keyboard (not shown) arranged on the heat pump 10.
  • the heat pump 10 comprises, in addition, a heat pump circuit and a water tank 11 with an inlet 13 at the bottom of the tank at which water enters that is to be heated up and an outlet 14 at the top of the tank at which heated water leaves the tank.
  • ': ⁇ he heat pump circuit comprises a circulating heat transfer medium in which the mostly liquid heat transfer medium 21 takes up heat from a heat source such as a rock heat loop 22, in which a cold medium such as glycol/water at a temperature of approximately -5° to +5° is circulated by a circulation pump in a water-filled borehole.
  • a heat source such as a rock heat loop 22
  • a cold medium such as glycol/water at a temperature of approximately -5° to +5°
  • the liquid heat transfer medium 21 takes up heat, it is vaporised in an evaporator 23.
  • the evaporating temperature can, for example, be -7°.
  • the gaseous heat transfer medium is then compressed by a compressor 24 to a higher pressure which, on account of the smaller volume of gas, means that the temperature of the gas is increased.
  • the compressed, heated gas (the hot gas) then gives off its heat via a condenser 25 and an undercooler 26 to the so-called primary water or the radiator water 27, while the gas is condensed to liquid.
  • the undercooling means that additional heat can be extracted and thus provides a more economical heat pump, while at the same time it is ensured that no bubbles of gas remain in the heat transfer medium when this reaches the expansion valve 28, via which the pressure of the liquid heat transfer medium is reduced considerably, whereupon the temperature of the heat transfer medium is reduced rapidly, after which the heat transfer medium again takes up heat from the rock heat loop 22.
  • the heating loop taking up heat from rock, it can take up heat from the soil, air and/or water.
  • the figure also shows an electric heater cartridge 29, which is only used when an extra provision of heat is required, for example, on very cold days, and a change-over valve 16 for changing between hot water production and heat production.
  • a circulating pump 17 is shown for circulation of the primary water.
  • the primary water heated up by the heat pump circuit is then used alternately to heat hot tap water and the property' s radiator and/or underfloor heating system.
  • the efficiency of the heat pump is governed by the condensing temperature of the heat transfer medium, in that the lower the temperature, that is the lower the pressure at which the condensing commences, the higher the efficiency.
  • the so-called coefficient of performance (COP) of the heat pump that is the ratio between output and input, can be 5, when it is heated to 50° it can be 3.4 and when it is heated to 60° it can be 2.5.
  • Figure 2a shows the system in Figure 1 with temperatures for an imaginary operating situation in which the property is heated by an underfloor heating system, and heating/circulating of radiator water in the underfloor heating system is carried out according to the loop provided with arrows .
  • the radiator water has a return temperature of 25°C when it is taken in at A in the undercooler 26.
  • the radiator water is heated to 35° while, at the same time, the temperature of the heat transfer medium is reduced from 66°C when it enters the condenser to 28°C after it has passed through the undercooler.
  • Figure 2b shows a corresponding enthalpy diagram and, as can be seen from the figure, in this operating situation a COP value (P OU T/P IN ) is obtained of approximately 5.
  • the upper part of the condenser 25 in Figure 2a acts as a hot gas heat exchanger, that is cooling of the hot gas from 66°C to 39°C takes place without condensing, and condensing does not commence until the temperature of the gas has reached 39°C.
  • Figure 2c shows the same system, but with temperatures for an imaginary operating situation where the hot tap water in the water tank 11 is heated up instead.
  • the primary water has a return temperature of 47 °C when it is taken in at A in the undercooler 26.
  • the primary water is heated up to 60° while, at the same time, the temperature of the heat transfer medium is reduced from 110°C when it enters into the condenser to 50°C after it has passed through the undercooler.
  • Figure 2d shows a corresponding enthalpy diagram and, as can be seen in the figure, a COP value (P OUT /P IN ) is obtained for the hot water production of approximately 2.5.
  • the fact that the increase in temperature is not larger is partly due to the fact that the heat-transfer surface of the hot gas part is relatively small, and partly to the fact that the flow is relatively large.
  • ⁇ is the flow of water
  • ⁇ T is the difference between the temperature of the water before and after the heat exchanger
  • k is a constant.
  • the primary water that has a return temperature of 47°C in Figure 2c after a large drawing off, has a lower temperature, perhaps only 20°C, on account of greater cooling during its passage through the tank 11, which in turn results in the heated primary water having a temperature that is lower than the 60°C shown, for example, perhaps as low as 30°C, which will further reduce the temperature at the top of the tank as heat is circulated downwards in the tank (the hotter water in the top of the tank heats up the primary water, after which the primary water transmits the heat to the colder water in the lower part of the tank) , and thus it can take a relatively long time before the temperature at the top of the tank reaches 50°C again and it is therefore possible to draw off a large quantity of water.
  • One way of making it easier to draw off large quantities of water is to increase still further the temperature of the heat transfer medium, and hence the temperature of the primary water. This is, however, carried out at the expense of poorer efficiency, for example, when the primary water is heated up to approximately 65 0 C, a COP is achieved of approximately 2.
  • FIG 3a shows an embodiment according to the present invention, according to which hot tap water can be produced at considerably lower cost in comparison with the known technology.
  • the heat pump 30 comprises a heat pump circuit and a water tank 31 with an inlet 33 at the bottom of the tank at which water enters that is to be heated up and an outlet 34 at the top of the tank at which heated water leaves the tank.
  • a circulating heat transfer medium 32 absorbs heat from a heat source, is evaporated and compressed.
  • the primary water is circulated through a unit 36 that comprises a condenser/undercooler, where the heat transfer medium transfers its heat to the primary water during the condensing/undercooling, whereby the primary water is heated to 35°C for circulation through an underfloor heating system by means of a circulating pump 41.
  • the primary water then passes through an electric heater cartridge 39.
  • a shunt valve is used that diverts a partial flow 42 from the primary water 37.
  • the remaining flow 43 of the primary water is circulated through the underfloor heating system in the property, while the partial flow 42, which can be regulated and can, for example, amount to 20% of the total flow, is taken to a hot gas heat exchanger 35.
  • the ratio between the heat transfer surface and the flow will be increased significantly, which results in the partial flow being able to be heated up to a considerably higher temperature.
  • the electric heater cartridge 39 enables additional heat to be supplied to the radiator water flow and/or the hot tap water flow, in response to the regulation of the proportion of the partial flow in relation to the total flow.
  • the partial flow is then used for heating up hot tap water which can thus be heated up to 55-60 0 C and has the same COP that would give 35 0 C according to the known technology.
  • the partial flow is taken out to the main flow to be circulated again.
  • radiators are used in the property instead, with the result that the radiator water is, for example, heated up to 60°C instead of 35°C, the present invention means that the partial flow can, instead, be heated up to an even higher temperature.
  • the temperature of the hot gas at the inlet to the hot gas heat exchanger is 110 0 C as in Figure 2c
  • the temperature at the top should be kept to a maximum of 95°C in order to avoid boiling.
  • the size of the improvement can easily be seen as it is the 40°C that is required at the taps that constitutes the reference point, and the actual temperature range for the mixing of hot water is thus 55°C (95-40) according to the present example, compared to 10 0 C (50-40) , which as a percentage is a very great improvement with the same COP that previously gave hot water at 50 0 C.
  • This has, in addition, the advantage that the danger of the growth of legionella bacteria can be considerably reduced, as the water is heated to a higher temperature, and, in addition, the tank can be heated through to a high temperature by operation of the heat pump, which reduces still further the need for the electric heater cartridge.
  • the flow can be regulated so that there is no condensing in the hot gas part of the heat exchanger.
  • the hot partial flow has the advantage that a rapid heating up at the top of the water tank is obtained and, on account of the stratification in the hot water reservoir, a certain quantity of usable hot water is obtained quickly in this way, even after a large amount has been drawn off. Even when the hot water reservoir has been emptied completely, recharging takes place quickly at the top and accordingly results quickly in a usable quantity of new hot water.
  • the solution according to the invention means, in addition, that considerably more hot water is obtained in comparison with the known technology, as the water is heated to a higher temperature, or alternatively the size of water tank for the heat pump can be reduced.
  • the flow of the partial flow can be regulated so that it is ensured at all times that the temperature of the flow that goes in at the top of the water tank does not drop below 50°C, or is at all times 5°C above the temperature at the top of the tank, however the temperature at the top of the tank should be kept to a maximum of 95°C as described above in order to avoid boiling.
  • the water in the radiators can be stationary, for example, for 20 minutes, while hot water is being produced.
  • the present invention has an additional advantage in that the accumulated water in the property's heating system can be used to speed up the heating up of the hot tap water.
  • This is exemplified in Figure 4. If there is a large withdrawal of hot water from the water tank, in an example with water at 50 °C in the radiator loop, the return temperature of the partial flow, that is the temperature after passage through the water tank, will be reduced from 70°C to, for example, 15°C as in Figure 4 (the figure shows the partial flow temperature after the withdrawal of hot water, for this reason the temperature of the partial flow in the figure is 67°C and not 70 0 C) .
  • This hot water at 15°C is then blended with the return flow of the radiator loop. If the partial flow constitutes approximately 9% of the total flow, as in the figure (16g/ (16g+168g) ) , this means that the return flow of the radiator water is reduced by approximately 2°C (according to the formula
  • Figure 5 shows yet another example in which an even larger part of the energy accumulated in the radiator system is "borrowed" for the production of hot water.
  • the partial flow is larger, approximately 58%, which leads to a lower maximum temperature of the partial flow.
  • the return temperature of the partial flow is slightly higher due to the larger flow, for example, 2O 0 C as in the figure.
  • This hot water at 20 0 C is mixed as before with the return flow of the radiator loop, which means that, in this case, the return flow of the radiator water is reduced by approximately 12 0 C, according to the above.
  • 58 litres of additional hot water at 40°C are obtained, with a through-flow time of 21 minutes in total.
  • control parameters can consist of one or more of the following:
  • the control can thus be arranged to give priority to different things at different times. For example, on certain occasions hot water production can be given priority, while in other cases heating of the property can be given priority.
  • the compressor can consist of a capacity-regulated compressor. This has, for example, the advantage that when hot water has been drawn off, the capacity of the compressor can be increased, provided that it is not already working at maximal capacity, so that the same feed pipe temperature is obtained at all times in spite of the colder return water.
  • Figure 6 shows an alternative embodiment of the present invention.
  • the return pipe of the partial flow 62 is connected to the outlet of the condenser 60.
  • this embodiment has the advantage that when the water tank 61 is fully charged, the return of the partial flow 62 can help to heat up the radiator water.
  • this has the advantage that, when the water tank 61 is charged, the return flow of the partial flow 62 does not increase the return temperature of the radiator water, which in turn means that the condensing temperature in the condenser is not raised, with improved efficiency as a result.
  • a changeover valve can be provided that can connect the return of the partial flow according to Figure 3A or Figure 6 in an adjustable way. In this way, the return of the partial flow can be connected at all times according to what is the most advantageous way at the time.
  • the present invention also has yet another great advantage.
  • the condenser is used, for example, for heating and the hot gas heat exchanger is used for other purposes.
  • the hot gas heat exchanger can be placed in the accumulator tank in order to heat up the surrounding accumulator water.
  • the need for heat in the accumulator tank can increase so much that the hot gas starts to condense in the hot gas exchanger, that is the energy required in the accumulator exceeds the energy available in the hot gas.
  • control computer ascertains that the production of hot water is insufficient, that is the return is too cold for a long period of time, for example two hours, in spite of it having been given priority, the partial flow can be closed off completely or reduced sufficiently for condensing not to take place in the hot gas heat exchanger, which is taken care of in a simple way by reading off the temperatures in the system and regulating the partial flow on the basis of these.
  • the device has only been described with a diverted partial flow.
  • the device can, however, be used in the normal way, particularly in summer, when no heating is carried out.
  • the whole flow is used for the production of hot water, and the heat pump operates, in principle, as in the known technology.
  • the hot gas exchanger 35 has been described solely as a hot gas exchanger.
  • the temperatures can, however, be regulated by controlling the flows and the compressor, which enables a certain amount of condensing to take place in the hot gas heat exchanger, or alternatively enables the condenser/undercooler 36 to be used partially as a hot gas heat exchanger.
  • the system can thus be optimized in all situations for the conditions to be found at the time.
  • Table I shows a summary of the most common operating situations (the heating modes) and at which COP the hot water is produced.
  • the heat transfer to the water in the water tank is carried out by means of a pipe loop. It is, however, of course possible to carry out this heat transfer in another way, for example, by the use of a jacketed water tank with an outer jacket that surrounds the tank, and where the partial flow is circulated through the space between the tank and the jacket, or with a different type of heat exchanger such as a plate heat exchanger or a charging heat exchanger, where radiator water is accumulated in a tank, and where the water at the top of the tank is circulated through the charging heat exchanger towards the hot tap water.
  • a circulation pump ensures, in this case, that the flow from the tank is sufficiently large to provide sufficient heating up of the hot tap water.
  • a shunt valve has been used to divert the partial flow.
  • a different device can be used for diverting the partial flow, for example a regulator can be used.
  • the condenser and the hot gas heat exchanger have been described as separate units. These can, however, also consist of an integrated unit, where the total flow is taken through a part of the integrated unit, and the partial flow is taken through a different part of the unit.
